Multiple sclerosis (MS) often leads to reduced physical activity and exercise participation. Sedentary behaviour is associated with poor health, whereas exercise is effective in managing MS symptoms. This study assessed physical activity, exercise and sedentary sitting time, and identified associations with symptoms.
Participants of the Australian MS Longitudinal Study completed surveys in 2016. We measured physical activity and sitting time via the International Physical Activity Questionnaire (short-form), and assessed participation in exercise (type and duration). Multivariable regression models assessed associations between physical activity, sitting time and exercise; and demographic characteristics and MS-related symptoms.
Of the 1216 participants, 53.0% reported moderate-high physical activity levels (71.5% among those with no/mild disability). Median sitting time was 7 h/day. Most (78.4%) participated in aerobic exercise, while only 16.4% participated in strength training. Having a progressive MS onset, more severe symptoms (i.e., cognitive impairment, depression, fatigue, mobility impairment) and being male was indicative of lower physical activity levels and higher sitting time.
Health promotion efforts should encourage physical activity and exercise, in particular strength training, among people with MS. People with more severe symptoms and progressive disease may require focused exercise promotion from healthcare professionals.Implications for RehabilitationComprehensive MS management should include strategies to increase physical activity and exercise participation, with particular focus upon people with higher MS-symptom burden (i.e., depression, fatigue and mobility and cognitive impairment), men, and those with progressive onset MS.Efforts to promote physical activity guidelines for people with MS and address barriers to physical activity must be implemented in standard MS care, with a particular focus on adhering to strength training guidelines.Exercise type and duration varies among people with MS, and it would behove healthcare professionals and researchers to consider promoting activities which align with individuals preferences and abilities when promoting exercise.
多发性硬化症（MS）常导致身体活动减少和运动参与度降低。久坐行为与健康状况不佳有关，而运动对控制MS症状有效。本研究评估了身体活动、运动和久坐时间，并确定了与症状的关联。
澳大利亚MS纵向研究的参与者于2016年完成了调查。我们通过国际身体活动问卷（简表）测量身体活动和久坐时间，并评估运动参与情况（类型和时长）。多变量回归模型评估了身体活动、久坐时间和运动之间的关联；以及人口统计学特征和与MS相关的症状。
在1216名参与者中，53.0%报告身体活动水平为中度至高度（无/轻度残疾者中为71.5%）。久坐时间中位数为每天7小时。大多数人（78.4%）参与有氧运动，而只有16.4%参与力量训练。MS发病呈进行性、症状更严重（即认知障碍、抑郁、疲劳、行动不便）以及男性表明身体活动水平较低和久坐时间较长。
健康促进工作应鼓励MS患者进行身体活动和运动，尤其是力量训练。症状更严重和疾病呈进行性的患者可能需要医疗保健专业人员重点推广运动。康复的意义综合MS管理应包括增加身体活动和运动参与度的策略，尤其关注MS症状负担较高（即抑郁、疲劳、行动和认知障碍）的人群、男性以及发病呈进行性的MS患者。必须在标准的MS护理中实施促进MS患者身体活动指南并消除身体活动障碍的努力，尤其要注重遵守力量训练指南。MS患者的运动类型和时长各不相同，医疗保健专业人员和研究人员在推广运动时应考虑推广符合个人偏好和能力的活动。
